About this model

I needed a way of cutting heat shrink tube into repeatable short lengths. It also needed to be safe and not have any exposed blades. the hole is 6mm sq, the largest I could make it without somebody getting their finger in it. It is all 3D printable, The only extras are the guide rods these are K&S stock #508 5/32 music wire that can be purchased at any model shop. A single edge razor blade and 2 light weight springs. WARNING Be very careful inserting the razor blade into the holder. As I have no control over your usage you accept full responsibility for building and using this tool. I had a request for a 50 mm cut capacity, I have added the STL for this. I have not printed it but it should be fine, please let me know if you have any issues with this. Updated 50mm base file due to rod hole …
